Powers:Doctor Light has the ability to manipulate ambient light for a variety of purposes. She can absorb all forms of illumination, and release that absorbed energy as blinding flashes or light, or destructive laser beams. She can refract light waves to create holographic images. Dr. Light can focus photons into "hard light" (radiant energy that is so tightly condensed that it almost becomes solid), and fire blasts of pure force or create protective barriers. She can fly by riding light waves.

Weaknesses:She needs a light source to fuel her powers, and being placed in an area of absolute darkness severely weakens her abilities.

Bio:Doctor Kimiyo Hoshi gained light-based powers while star-gazing during the earth-shattering Crisis. These powers are formidable, having many applications beyond simply blasting light at an opponent. She is a single mother, and after a period as a well-respected member of the Justice League, she decided to devote more time to her family than to super-heroics, only emerging briefly from retirement in times of the direst need. She is currently the vice president of Kordtech's research and development division and will soon take over as president of the entire organization.
